Problems solved by technology

The swapping process can be time consuming, and the reliability of the host printing system can be jeopardized.
In particular, over time, the repeated insertion and removal of image data interface cards (IDICs), along with associated interface connectors, can be harmful to the system.
There are several risks associated with continued insertion, including: static discharge damage to the boards, damage to an associated backplane due to disconnect connect cycles, and damage to fiber-optic or other interface cables.

Embodiment Construction

[0014] Referring to FIG. 1, there is shown a simplified elevational view of several elements of an exemplary prior art color printing apparatus. The exemplary color printing apparatus, designated by the numeral 8, employs an “image-on-image” xerographic technology in which successive primary-color images are accumulated on a photoreceptor belt, and the accumulated superimposed images are in one step directly transferred to an output sheet as a full-color image. As will appear, other monochrome or color printing apparatuses, using xerographic or ink-jet based technologies, would be suitable for use with the disclosed embodiments.

[0015] As shown in FIG. 1, the prior art printing apparatus 8 includes a belt photoreceptor 10, along which are disposed a series of stations, as is generally familiar in the art of xerography, one set for each primary color to be printed. For instance, to place a cyan color separation image on photoreceptor 10, there is used a charge corotron 12C, an imagin...

Abstract

A printing system for producing prints from a print job is provided. The printing system includes first and second digital fronts ends as well as an image path. The image path communicates selectively with the first digital front end and the second digital front end, and receives (1) printable information from the first digital front end when the first digital front end and the image path are configured in a first mode, and (2) printable information from the second digital front end when the second digital front end and the image path are configured in a second mode. A selection system disposes the first digital front end and the image path in the first mode, or the second digital front end and the image path in the second mode.

Description

BACKGROUND AND SUMMARY [0001] The disclosed embodiments relate to an improved control system for a printing system and, more particularly, to a switchable digital front end (DFE) implementation permitting multiple digital front ends to be selectively used with a single print engine. [0002] Digital printing systems can be as simple as an office laser printer or can be room size devices that include multiple paper feeders, multiple mark facilities (for example a black and white unit and a color unit), collators, staplers and shrink wrappers. Larger standalone systems, such as the Xerox iGen3™ 110 Digital Production Press include an input module, sometimes referred to as a “digital front end (DFE),” in which various operations are performed on an incoming print job. An example of a complex DFE, performing such operations as decomposition, image processing, and image editing is described in U.S. Pat. No. 5,493,634, the pertinent portions of which are incorporated herein by reference. [0...
